The tablets are just the latest mobile devices to be unveiled by AT&T in the last few days. Both 4G LTE products, which run on the next-generation Windows operating system, will be available for the holiday season, although the company didn't specify when or at what price.

While the iPad has been a runaway success, few other tablets, particularly ones connected to a cellular network, have been successful. AT&T is hoping for a change with the introduction of Microsoft's next version of Windows.

The ATIV, part of Samsung's Windows lineup of smartphones and tablets, comes with an 11.6-inch high-definition PLS display, an Intel Clover Trail 1.5-gigahertz dual-core processor, and 64 gigabytes of internal storage. It runs on Windows 8 and comes with a trial version of Microsoft Office 2013, including Word, Excel, and Powerpoint.

The device has a detachable keyboard-docking system allowing it to switch between a notebook PC and tablet PC.

AT&T is hoping for a pick-up in sales of tablets with the introduction of family data plans. The plans are designed to make it easier for consumers to bring multiple devices under one plan, using a shared bucket of data.
